1. All timing is referenced to the 50% level of the waveform. Input test levels are V
2. FSYNC source is assumed to be 8 kHz under all operating conditions.
3. Specification applies to PCLK fall to DTX tristate when that mode is selected.
= 3.13 to 5.25 V, T
Rise and fall times are referenced to the 20% and 80% levels of the waveform.
